POLAR COACH WRIST RECEIVER
The estimated average battery life of the Polar Coach receiver is 1 year
in normal use (1h/day, 7 days a week). However, because the battery is
inserted at the factory, the actual life of your first battery once in your
possession may be less than the estimated battery life. Note also that
excessive use of the backlight and the alarm signals will use the battery
up more rapidly.
Do not open the Polar Coach wrist receiver yourself. To ensure the
retention of the water resistance properties and the use of authorised
components, the wrist receiver battery should be replaced only by a
authorised Polar Service Centre. At the same time a full periodic check
of the Polar Heart Rate Monitor will be done. Service for detailed
instructions.
